natulia [17]

Options for the question are not given. They are as follows:

a. arg or lys

b. ala

c. thr

d. leu or ser

e. Only termination codons

Answer:

d. leu or ser

Explanation:

Four codons code for proline amino acid. These are CCT, CCC, CCA, and CCG. Hydroxylamine causes C to change into T or G to change into A.

If first position is changed in each codon:

CCT = TCT (UCU)

CCC = TCC (UCC)

CCA = TCA (UCA)

CCG = TCG (UCG)

These codons produce Serine amino acid.

If second position is changed in each codon:

CCT = CTT (CUU)

CCC = CTC (CUC)

CCA = CTA (CUA)

CCG = CTG (CUG)

These codons produce Leucine amino acid.

Hence, out of the given options, option d. leu or ser is correct.

With the assumption that schmid-type metaphyseal chondrodysplasia is rare, is this type of dwarfism inherited as a dominant or r
Marrrta [24]

Answer and explanation;

-The nearly one-to-one ratio seen in the offspring suggests it is likely inherited as a dominant trait, with the dwarf parent being heterozygous for the dwarf allele along with the normal parent being homozygous for the normal allele.

-Metaphyseal chondrodysplasia, Schmid type (MCDS) is a type of skeletal disorder in which there is abnormal bone formation at the end of the long bones (metaphyses).  MCDS is caused by a mutation in one of the collagen genes. The MCDS mutation is passed on in an autosomal dominant manner.
