A scientist isolated a molecule with nucleotide bases A, C, G, and U and ribose sugars. What is it?

gogolik [260]

Answer:

The Answer is RNA.

Explanation:

Because RNA consists of four nitrogenous bases: adenine, cytosine, uracil, and guanine. I am 100% sure that is the answer if it's wrong, very sorry.

Short note sentence describe the terms pure culture and mixed culture

yaroslaw [1]

Answer:

A pure culture consists of only one type of microbe while a mixed culture has two or more than two microbes.

Explanation:

A pure culture consists of only one type of microbe.

While a mixed culture consists of more than one type of microbes. such cultures may comprise of different species of bacteria or a group of bacteria, viruses and other pathogens.

In mixed culture the microbe species living together may harm each other existence.

A biologist at World University used Procedure IV to conduct an additional study and found the sequence following below. Using y

Nady [450]

Answer:

Valine-Leucine-Proline-Lysine-Histidine

Explanation:

The central dogma of biology is the process by which DNA is used to synthesize RNA and subsequently amino acid sequence (PROTEIN). The processes of transcription and translation is used in gene expression. Transcription is the process whereby the information encoded in a DNA molecule is used to synthesize a mRNA molecule. Transcription is catalyzed by RNA polymerase enzyme, which uses complementary base pairing rule i.e Adenine(A)-Thymine(T), Guanine(G)-Cytosine(C) pairing.

N.B: Thymine is replaced by Uracil in the mRNA

For the above DNA sequence: CAC GAC GGA TTC GTA, the mRNA sequence will be: GUG CUG CCU AAG CAU

Translation is the second process of gene expression which involves the synthesis of an amino acid sequence from an mRNA molecule. The mRNA is read in a group of three nucleotides called CODON. Each codon specifies an amino acid (see attached image for genetic code)

Based on the attached genetic code, an mRNA sequence: GUG CUG CCU AAG CAU will encode an amino acid sequence: Valine(Val) - Leucine (Leu) -Proline (Pro) -Lysine (Lys) - Histidine (His).

GUG specifies Valine amino acid

CUG specifies Leucine amino acid

CCU specifies Proline amino acid

AAG specifies Lysine amino acid

CAU specifies Histidine amino acid
