What means RNA and it shape in the biology

Biology
2 answers:
MaRussiya [10]3 years ago

The Answer is ribonucleic acid, a nucleic acid present in all living cells. Its principal role is to act as a messenger carrying instructions from DNA for controlling the synthesis of proteins, although in some viruses RNA rather than DNA carries the genetic information.

RNA is typically single stranded and is made of ribonucleotides that are linked by phosphodiester bonds.

I hope this helps you:)

Answer:

<u>RNA means</u>

RNA, abbreviation of ribonucleic acid, complex compound of high molecular weight that functions in cellular protein synthesis and replaces DNA (deoxyribonucleic acid) as a carrier of genetic codes in some viruses

<u>RNA shape</u>

RNA is typically single stranded and is made of ribonucleotides that are linked by phosphodiester bonds. 1. RNA contains the pyrimidine uracil in place of thymine found in DNA. Figure 2. DNA is typically double stranded, whereas RNA is typically single stranded.

Answer and Explanation:

Achondroplasia is a form of dwarfism that affects the formation of cartilage; early in development, most of the skeleton is comprised of cartilage. Cartilage is a type of flexible, tough tissue; in achondroplasia ossification (conversion of cartilage to bone) is affected. Symptoms include an enlarged head, shorter upper and lower limbs, and limited motion at the elbow.

Punnett squares are illustrations that display the product of hybrid trait crosses by genetic breeding.

For this cross...

Assuming Achondroplasia= dominant

Parent generation or P generation:

gametes: An → Achondroplasia dominant (A), No Achondroplasia recessive (n)

Heterozygousity describes the allelic makeup; these traits comprise two varying forms of a  gene. However, homozygous traits comprise identical forms of the gene.

Male: An  →  with Achondroplasia

Female: nn → without Achondroplasia

genotypes and phenotypes for parent and offspring...

Assuming heterozygousity of the male , for the cross

P generation:                         An × nn

                          Achondroplasia   × No Achondroplasia

F1 generation:

genotype:                      An × nn       ...(from punnet square)

phenotype:          2 with Achondroplasia ; 2 without

∴ 50% are genotypically heterozygous while 50% is homozygous , 2 with Achondroplasia ; 2 without
